So what do you think the problem is please ?
Dear Greefus, I do not know, because I do not have your microphone, I can only guess it may be caused by the processing you used, but recording techniques are not my specialty.
I suggest trying another microphone you know on your device and comparing the two in the same way the video I linked to did.
That is:
1. Disable all processing, just adjust your gain to enough input.
2. make sure you can reproduce the same output levels of the mic's you compare.
this means you start with something that outputs a constant tone at a repeatable fixed volume and fixed distance, for instance your phone and a tone generator app at 1 KHz.
When you switch mic's, you adjust the gain so your input level monitor shows the exact same value +/- 1 dB.
3. record mic 1 with a text you know well, or try to repeat a line from the video
4. switch to mic 2 and adjust gain
5. record mic 2 with the same text
compare these two, and compare it with the recordings from the video.
And maybe play around speaking real close to your mic,
hope that helps, good luck!
